Everything is rosy in Sheffield United's garden right now as they sit three points clear at the top of the Championship on the back of a nine game unbeaten run.
They have won the last four, while it is a maximum four wins out of four at Bramall Lane with 11 goals scored and just the one conceded.
Since Paul Heckingbottom took over last November, the Blades have only lost two out of 19 in S2.
They will expect three points from a Birmingham side, down in 17th but unbeaten in their last three with successive wins on the road.
